New brain scan technology could save babies' lives

...the brain is working. In optical tomography, light passes through body tissue and is then analysed by computer to provide information about the tissue. A helmet incorporating 32 light detectors and 32 sources of completely safe, low-intensity laser light is placed on the baby's head. The sources produce s...

'Acid rain' and forest mass: Another perspective

... transcolation (fraction of the precipitation that passes through the forest canopy), and litterfall (vegetable material fallen from trees: leaves, twigs, fruit, and so on), the first 25 cm of mineral soil and green foliage were taken and analysed chemically, according to standard protocols. The location o...

'Smart' nanoprobes light up disease

...nt in biomedical imaging. Near-infrared light also passes harmlessly through skin, muscle and cartilage, so the new probes could alert doctors to tumors and other diseases sites deep in the body without the need for a biopsy or invasive surgery. The probe's design makes use of a technique called "quenching...

Purdue researchers find key to rice blast fungus

...e. This pathway is the communications highway that passes information and instructions from one molecule to another to cause biochemical changes. The fungus spreads when its spores are blown to rice plants and stick on the leaves. Once on the plant, the spore forms a structure called an appressorium. This ...

A step toward the $1,000 personal genome using readily available lab equipment

...f the base. Recording the color data from multiple passes over the same sequences, a camera documents the results and routes them to computers that reinterpret the data as a linear sequence of base pairs. In their study, the researchers matched the sequence information against a reference genome, finding g...

NHGRI expands effort to revolutionize sequencing technologies

... the basis of changes in electrical current, as it passes through a membrane with tiny channels known as nanopores. Jene A. Golovchenko, Ph.D., Harvard University, Cambridge, Mass. $5.2 million (3 years) "Electronic Sequencing in Nanopores" The objective of this project is to develop a general utility ins...

Hanging baskets of sex and death help fruit growers

... frustrated but covered in the virus which it then passes on to other moths when it does manage to have an actual encounter with another real moth. This results in direct contamination of eggs laid by the pest or contamination of the site where the moth lays its eggs. The larvae are killed after eating the ...

Visceral Leishmaniasis: Successful Vaccine Trial In Dogs

...single bite. Once in the blood stream, L. infantum passes into particular cells of the immune system, the macrophages. These eventually burst, releasing the parasites which move on to penetrate other cells. The infected subject suffers bouts of fever, anaemia, enlarged spleen and liver, and weight loss. In ...

Device traps, disables harmful bacteria

...d after the filter there is UV light; if something passes through the filter, the UV zaps it. It's a combination approach that appears very effective. The bacterium that had been causing illness was Mycobacterium avium, which can make immunocompromised people ill, and since a lot of elderly use therapy pool...

Secrets to antibody's success against West Nile Virus surprise scientists

...turn antibodies that should be death warrants into passes into cells where invaders can reproduce. Fremont cautions that this phenomenon has not been seen in West Nile virus, but notes that when he and his colleagues tested the ability of several antibodies to prevent West Nile from reproducing inside ma...

It's electric: Cows show promise as powerplants

...cellulose to feed microbes, as some plant material passes undigested through a cow. "We've run some of these trials well over 30 days without a decrease in the voltage output," Christy said. "Both studies suggest that cow waste is a promising fuel source. It's cheap and plentiful, and it may someday be a u...

Scientists reveal the shape of a protein that helps retroviruses break into cells

... cut off from each other because even low-altitude passes had insufficient oxygen to allow animals to cross ... and animals that once were able to cross mountain passes quite easily suddenly had their movements severely restricted," Huey said. He calculated that when ...

Low oxygen likely made Great Dying worse, greatly delayed recovery

NIH Researchers Discover How Insulin Allows Entry of Glucose Into Cells

...pe’s lens. However, residual energy from the light passes through the cover slip, to the cell beneath, illuminating the area just below the cell’s surface while leaving the inside of the cell dark. “When we started the experiment, we thought that the vesicles would be stationary,?Dr. Zimmerberg said. “The ...
